CAR-COUPLING.

SPEGIFIGATION f0rming part of Letters Patent No. 285,247, datedSeptember 18, 1883.

Application filed June 12, 1883.

(No model.)

To aZZ whom it may concern:

Be it known that I, BnvLY A. FIsHER, of St. James, Phelps county, andState of Missouri, have invented a new and useful Improvement inSelf-Couplers for Railway-Oars, of which the following is a full, clear,and eX- act description, reference being had to the ac companyingdrawings, making a part of this specification, in which- Figure 1 is asection of two draw-heads,

showing my improvements attached. Fig. 2'

is the same, showing the coupling-ring in position. Fig. 3 is a planview of same.

My invention relates to self -couplers for railway-cars; and it consistsof the combination of devices hereinafter explained and claimed.

To enable others skilled in the art to make and use my invention, I willproceed to describe the exact manner in which I have carried it out.

In the drawings, A A are the draw-heads of two cars, and B thecoupling-rings. G is the coupling-pin, made as shown in Figs. 2 and 3,and pivoted at the rear of its center of gravity, so the forward part ofthe pin will fall from gravity and stand normally as shown at c inFig. 1. The rear portion of the pin 0 is provided with the upwardprojection 0, against which the coupling ring B strikes as it enters thedraw-head, forcing down the rear of the pin 0, and causing the front torise and catch the ring and hold it in place. In the rear of theprojection C is a fiat step, c, tobe here- In order to hold the pininafter explained. up to its work after it has passed through the link,as shown in Fig. 2, in the rear of the pin I pivot the tumbler D, sothat its rear end, (1, will be heavier, and it will normally hang asshown in Fig. l; but when the link enters the draw-head and forces downthe rear of the pin the forward part of the tumbler D will swing overand rest upon the step c, as shown in Fig. 2, thus securing thecoupling-pin O in position to hold the coupling-link and prevent thepossibility of the cars becoming accident ally uncoupled. Through thetumbler D passes the lever-rod F,with its crank F, by the raising ofwhich the tumbler is caused to swing from the step c and allow the pin 0to drop out of the coupling-link, as shown in Fig. 1. In order to securea simultaneous movement between the tumbler and the pin, they areconnected by a small chain or cord, 6, so that as the rear of thetumbler is raised by the lever the chain or cord will draw down the pinand release the link.

The cranks F F can be extended to the side of the cars, and, if desiredto be connected by rods or chains, to the top of the cars, so thatthecoupling and uncoupling of the cars may be easily accomplishedwithout requiring any one to pass between the cars, thus avoiding alldanger to the operative.

Having thus explained my invention, what I claim, and desire to secureby Letters Patent, is-

In an automatic railwaycoupler, the pivoted pin 0, provided with theupward projection 0 and the step c, in combination with the pivotedtumbler D, lever-rod E, with its crank F, and cord c, all constructed tooperate substantially as and for the purpose set forth.
